If it's a pub gig, in a pub, usual load-in, start and stop times, then it's a pub gig. Pub gig money. I always think if there's a party in there, more people will see the band that probably wouldn't have bothered.
I've even done private functions for pub gig money. I tell them, 'if I can treat it like a pub gig, arrive at 7.30, start at 9 finish by 11.30, then I'll do it for pub gig money.
